10 Generic USB Mic+Webcams 10 Port Powered USB HUB A buttload of USB extension cables I havent decided on the software yet, but it may be iSpy or YAWCAM

As for the computer, I honestly do now know what I should be looking for. A cheap prebuilt one is nice, but I was looking forward to build my own. The last computer I built had:

AMD Phenom 2 x6 4GB DDR3 Radeon HD 4890 for $280 on black friday.

Obviously that is my gaming rig, my parents own a store in CA and I want to set up a cheap surveillance system for them. The features I'm looking for in the system goes for $500-$2000 on average and I'm not looking forward to paying that much. The cameras and hub already cost me $170 even in a bulk order.

So this is the first time i'm looking forward to build a computer not bent on the best gaming performance. I'm looking for an extremely cheap build that would be able to do motion detection and sound detection for 10 cameras and stuff like that.

I'm looking to have 2 2TB Drives and a SSD Boot drive in read only mode. I'm not looking forward to spending more than $300 for this computer, I just need a recommendation for CPU and RAM. Motherboard is usually something I can find on my own. GPU, I dont think a system like this is very GPU intensive. Assume I already have an ATX case, 480 watt PSU 20+4, DVD Drives, Floppies and all that.

Any other tips on those who already have one would be gladly appreciated. _______________________ mother board
